Chris Young Back Home After Surgery

Chris Young has returned home after four days in a Denver, Colo. area hospital.

The singer says he's on the mend after undergoing leg surgery. He was taken by ambulance to the hospital last week after falling ill on a flight.

Young's tweet leaves roomer to doubt his immediate touring future. Initially, he was thought to only miss shows through last weekend and return for the Aug. 21 headlining show in Redding, Calif., and then his opening dates for Brad Paisley's Beat This Summer Tour. An inquiry to his representatives was not immediately returned. The Civic Auditorium in Redding still lists the show as scheduled.

Young was initially put in intensive care to treat the mystery infection, but he was moved to a normal room on Thursday (Aug. 15). He was walking around last week, and had his mother, Becky Harris, by his side.
